Unfortunately I do not understand or find a way to do several things and I hope someone here will be able to help me...

First, with a ZIP file containing the tiles I need, how can I set it to the OSM mapview in order to use it offline ?

Then, I have a rotating arrow UI Component (extending View) which must refresh often. It currently works with GMaps, but with OSM map, it seems the "draw" event is only called once. (When i drag the OSM Map, my rotating arrow refreshes !). Does anyone has an idea why ?
